A lot of power out of a
relatively compact, lightweight package (about 50 pounds).

Inexpensive tube replacement
- Chinese 572B's work great and can be had for about $200 for the whole
set of four (4).

Operates on either 120 or
240 VAC power supply is built in.

A lot of "bang for
the buck" as amplifier will output in excess of 1KW and are still
plentiful & inexpensive.

Low profile - the four (4)
572B tubes are mounted horizontally - so entire unit is only 6 3/4"
high (including the feet)

572B's are correctly mounted
for correct filament alignment.

As of this writing (2011)
units are around 30 years old (not quite as old as most of the Heaths
and 30L-1's floating around).

Cons:

No longer in production

Not exactly stellar construction.

Stock unit suffers from
60 Hz. hum due to improper feed of directly heated cathode 572-B finals.
Output is actually modulated by the AC filament power (no transformer
center tap). Dentron pushed the cost cutting envelope too far in this
design - BUT - an easy fix. Modification
highly recommended and should only cost about $20.00.

NOT tuned input - designed
to be driven with tube output exciters. My unit has a broad band matching
input board - modern rigs will drive with a tuner. Very late versions
of this amplifier had tuned input circuits for each band (rare - not
many were produced).

Not designed for continuous
modes OR continuous duty. I have had many QSO's running AM - BUT - I
kept the plate voltage in the low voltage "CW" position and
ran no more than 100 watts output (roughly 330 watts input).

Fan is noisy and constantly
changing speed due to series feed through a resistor.

Be VERY careful when buying
a Clipperton-L - many ended up on 11 Meters over the years. Be prepared
to spend some extra money and time after purchasing one of these amplifiers
(for filter caps, fan, mods. & probably a set of final tubes). Also,
many of these amplifiers have been abused and now have soft finals.

Low output on 160 Meters
due to pi-network coupling to the enclosure - see
VE3NH for data.
